The AU87101A (often paired with the AU89101) is a high-performance Alcor Micro USB 3.0 controller chip. If you are seeing a "UFDisk full" error or your drive is corrupted, it typically requires specialized "Mass Production" (MP) tools to reset the firmware and restore the drive's capacity. Phase 1: Identify Your Hardware

Before downloading tools, you must confirm your drive's exact specifications, as using the wrong firmware can permanently "brick" the device.

Download ChipGenius: Use this utility to retrieve your drive's VID (Vendor ID), PID (Product ID), and Flash ID. Standard Alcor VID/PID: Usually 058F/6387.

Check for "Fake" Capacity: If your drive shows a high capacity (e.g., 1TB) but only allows a few gigabytes of data, it may be a "fake" drive that needs to be reformatted to its actual physical capacity. Phase 2: Use Repair Tools

To fix "Full" or "No Media" errors, you need the Alcor MP (Mass Production) Tool. au87101a ufdisk full

Download the Tool: Look for versions supporting the AU87xxx series on specialized repositories like USBDev.ru or FlashBoot.ru.

Run as Administrator: Right-click the .exe and select "Run as Administrator."

Insert the Drive: If the tool does not detect it, you may need to use Alcor Change PID/VID Rework to reset the identifiers to the default 058F/6387.

Start Formatting: Click Start to begin the firmware update and low-level format. This process will erase all data. Phase 3: Troubleshooting "UFDisk Full" If the MP Tool fails or the drive is still "full":

Check Write Protection: Some Alcor drives have a physical switch or a software lock that triggers "full" errors. Use the QCTOOL utility to toggle security settings. The proper text for the error message au87101a

Test for Bad Blocks: Use H2testw after repair to verify that the restored capacity is stable and not prone to data corruption. IC Alcor Micro - USBDev.ru

5.4 Schedule regular ufdisk health checks

Monthly, run:

ufdisk -v au87101a          # Verify structures
ufdisk -e au87101a          # Estimate future fill rate

AU87101A UFDISK Full — Recovery & Repair Guide

Part 1: What is the AU87101A?

The term AU87101A refers to a specific USB Flash Drive Controller Chip manufactured by Alcor Micro (often abbreviated as Alcor).

A USB drive consists of two main physical components:

  1. The NAND Flash Memory: Where your data is actually stored.
  2. The Controller: The "brain" of the drive that manages how data is written to and read from the memory chip.

When a USB drive fails with errors like "UFDisk Full" or "No Media," it is rarely the memory chip that has died; it is usually a corruption of the controller's firmware. The controller has entered a "safe mode" or has lost its partition table information, causing Windows or macOS to misinterpret the drive's capacity and status.

Part 2: Understanding the "UFDisk Full" Error

The error message "UFDisk Full" or seeing a drive with 0 bytes available is a classic symptom of a Corrupted Flash ID or Firmware Glitch.
